Application

MCCB is supplied with rated insulation voltage 800V(63 type is 500V) and used for circuit of A.C.50Hz or 60Hz,rated operating voltage AC 690V or below. Rated operating current from 10A to 1500A for infrequent changing over and starting of the motors. Equiped with the protection devices for over-current. short circuit and under voltage. The product is capable of preventing damage of circuits and supply units.
     The breakers are of the following characterstics:compact size,high breaking capacity,short arc-over distance and shake proof,etc.
     The product conforms to IEC60947-2,GB14048.2 standard.
     According to the rated ultimate short-circuit breaking capacity(lcu),the breakers are classified into three kinds of types:L(standard breaking type),M(second high breaking type),H(High breaking type).
     The breakers could be installed vertically(upright) or horizontally(transverse).

Application environment condition

1.Ambient temperature:-5℃ to +40℃
2.Height above sea level≤2000m.
3.Relative humidity: not exceeding 50% at the maximum ambient temperature of +40℃.
4.With lower temperature, higher humidity would be permitted, but the lowest average temperature +25℃ in a month relative humidity not exceeding 90%, and giving consideration to the dews on the goods surface, which would appear due to temperature change.
Pollution protection:3 grade
